To @ZZ whom t may conce/Mt:

Be it known that L HOHER P. CHANDLER, acitizen of the United States ofAmerica, residing at Mansfield, in the county of Richland and State ofOhio, have inventedV certain new and useful improvements in ConductorSupports, of which the following is a. specication.- l

My invention relates to conductor supports and more, particularly tothat class of support for securing a trolley wire to an overhead hanger.

@ne of the objects of my invention is to produce a device which can besecured to a hanger, and then. .have the jaws which grip the trolleywire aline with the trolley wire without disturbing the relation betweenthe clamp and the hanger, and then to move the jaws into grippingengagement with the trolley wire. Another object of my invention is toproduce a device in Vwhich the jaws can lbe alined with respect to thehanger, and in which the jaws can ybe positively moved into or out ofengagement with the trolley wire. Other objects will be disclosed tothose skilled in the artv 'from the description herein of my preferredform of construction.

My invention resides in the new and novel construction, combination andrelation of the various elements of which the invention is composed asherein described and shown in the accompanying drawing.

ln the accompanying drawing: j

Fig. 1 is a side view in elevation of my complete invention shown asengaging a trolley wire.

Fig. 2 is an end view of Fig. 1.

Fig. 3 is a sectional view of my invention taken on the line 3-3 of Fig.1, showing a hanger in combination therewith and the jaws open toreceive the trolley wire. n

Fig. 4 is similar to Fig. 3 excepting the jaws are shown in grippingengagement with the trolley wire.

Fig. 5 is a sectional view on the line' 5 of Fig. 4, and showsmeans'whereby two of the elements have a limited relative rotation withrespect to each other.

In the preferred embodiment of my in- 1923. Serial No. 635,872.

member 4 is provided with an internallyy projecting flange 5 whichengages and rests upon the flange 3 and is supported thereby.

Erice. A

YThe thickness of the flange 5 is preferably slightly less than thedistance from the upper face of thevfiange 3 to the upper face of thesupporting member` 1, so that when the device is installed upon thehanger H i the operating member 4 will not bind, butwill be free torotate relative to the supporting member 1. The operating member 4 isprovided with an internally threaded supporting member 1 is providedwith a projecting lug 9 which engages with a. projecting lug 10 on theintermediate member 7. lt will be seenfrom Fig. 5 lthat the members 1and 7 are free to rotate relativeto i; each other, but have the saidrotation lim- I ited by the engagement of the lugs 9.and lOl Projectingfrom the lower end of the member 7 is a lug 11 provided with an openingto receive the pin 12. Securedto the lug 11 are two 'jaw members 13provided with means 14 at their lowerends to engage a trolley wire 15.rAdjacent the upper end of the jaws 13 vand projecting inwardly arelugs'16, and held in position with respect to the lug 11 by means of thepin 12 whereby the jaws are permittedY to swing' about the axis of thepin 12, but cannot rotate votherwise with respect to the lug 11.

The jaws 13 are each provided near its upper end with an annular groove17 formedfby the adjacent anges 18 and 19,

Y and said groove may extend lentirely around kthe circumference of eachjaw 13 or only part way around, depending upon the eX- tent of theflanges 18 and 19. Positioned within the groove 17 of eachpjaw 13 is aflange 2O projecting from the lower portion of the operating member 4.The flange 20 engages the flange 19 to move the jaws' 13 intokengagement with the trolley wire and to hold them in said engagement.The flange 2O engages the flange 18 tomove vention lY employ asupporting member 1 :the jaws out of engagement with the trolleyinternally threaded to engage the threads on a stud 2 of the hanger H.kThe supportl ing member 1 is provided with a flange 3 to support anoperating member 4. The' wire or to open them to receive the trolleywire and to maintain the jaws in an open position. The jaws 13 and theoperating' member 4y are free to rotate relative toeach i other. memberyis provided with a heldagainst a longitudinal movement with respect tothe member 1, but the member 7 can move longitudinally with respect tothe member 1 when the member l is rotated in either direction. It willalso be observed that there is substantiallyno relative longitudinalmovement of the member d with respectto the upper outer portions of thejaws 13 other than a pivotal action therebetween, andsthat the lugs 16move with' the member The `operation of installing my invention` uponthe hanger consists in first grasping the jaws lipreierably with thehands and in placing the member 1 in engagement with thestud 2 of theliangerfH. -the aws are now rotated in tlieproper direction the lug 10will be brought into engagement with the' lug ,9, and when thisrengagement taires place further rotation oir the jaws will rotate themember 1 intofull and secure engagement witlithe stud 2 until the upperface oiC the member-1 engages the -lower face of the hanger i After thisoperation the jaws 18 may not be in alinement with the trolley wire, but`this, alinement' can be brought about byreversing the direction otrotation of the jawsand this reversal of rotation will not rotate themember 1, as the amount of back rotationl would not-exceed 186 degreesandthere is a possible relative rotation of the vmembers 1 and 7 ot lessthan 360 degrees, dependin vupon the thickness ofthe lugs 9 and 10.lavi-ng alined the jaws with respect tothe trolley wire, it the jaws arein a closed position so as not toreceive the trolley wire, the operatingmember eiis rotated in a proper direction to cause the member 7 to movedownwardly due to the threaded engagement, and this will cause the jawsto pivot about their pointotengage- A. ment with the operating memberand thereby force the jawsvto. open. Having opened the awskthe trolleywire is placedV in position between the jaws, and the operatingmember isthen rotated lin a direction to cause the member 7 to move upwardlyA'until the aws engage the trolley wire. wrench is now applied to the-faces 21 ofthe operating member #l and further rotation or the member tby means of the wrench will force theaj aws into further and secureengagement with the trolley wire.

ln Fig., 5 the lugs 9 and 1() are shown in separated, is illustrative ora position which the lugs may take after the jaws have been alined withrespect to the trolley wire.

Modiiications will occur to those skilled in the art from .thedisclosure which l have herein made, but l do not wish to be limitedother than by my claims.
